The arrogance of some who think they "know you" based on arm's length sporadic interaction is ludicrous. It takes YEARS to get to know people and even then you never can really entirely know anyone. Snapshot assessments. Snapshot "conclusions. Why do people think they KNOW so much more than they possibly can KNOW about others? They can guess but all guesses are filtered through the lens of self-preservation. Whatever makes them look good and feel good about themselves is what they think about others. SIGH. As time goes by it seems people become more sure of themselves, more full of themselves, more CERTAIN about others. WHY?
